Abstract

The use of a foam roller has become increasingly popular among athletes and casual exercisers; however, few studies have investigated the effects of foam rolling on subsequent exercise performance. This study was conducted using 24 healthy participants between the ages of 18 and 35 years who exercised at least three times a week. They each completed a familiarization with baseline and post-condition measurements made in the vertical jump test (VJ), pro-agility test (PA), modified weight bearing lunge test (WBL) and modified kneeling lunge test (MKL). In a partially randomized but balanced order, each subject was asked to perform three conditions: supported planking on a heating pad (control), 1-min foam roll (FR), or 5-min FR. Four 3 x 2 repeated measures analysis of variance (ANOVA) were used to determine whether there were significant differences between the three conditions (control, 1-min FR, 5-min FR) at two times (pre-FR, post-FR) in VJ, PA, WBL, and MKL measurements. The 5-min FR and control condition negatively affected VJ performance while the 1-min FR had no such effect. Furthermore, the 5-min FR exhibited a significantly greater negative effect on VJ performance than the control. The control showed a significant decrease in PA while the 5-min FR did not negatively affect PA performance and the 1-min FR increased PA performance. In the WBL, the 1-min and 5-min FR significantly increased range of motion (ROM) compared to the control. In the MKL, the 1-min and 5-min FR both significantly increased range of motion with the 5-min FR showing significantly greater increase in ROM. These data show that increased 5-min of foam rolling may decrease VJ or power performance but increases ROM to a greater degree than 1 min of foam rolling.
